Tohaina
Kua tāruatia ki te papatopenga
k+8-4k=40
Whakareatia ngā taha e rua o te whārite ki te 4.
-3k+8=40
Pahekotia te k me -4k, ka -3k.
-3k=40-8
Tangohia te 8 mai i ngā taha e rua.
-3k=32
Tangohia te 8 i te 40, ka 32.
k=\frac{32}{-3}
Whakawehea ngā taha e rua ki te -3.
k=-\frac{32}{3}
Ka taea te hautanga \frac{32}{-3} te tuhi anō ko -\frac{32}{3} mā te tango i te tohu tōraro.
